To all whom it may concern.-

lBe it known that 1, CHARLES S. Locxwoon, a citizen of the United States, whose residence and post-ofiice address is 289 Market street, Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Roller-Bearings, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present invention relates to an improved construction for the thrust-collar in a roller-bearing, and comprises a casing and a journal having shoulders facing in the same direction, a thrust-collar fitted to one of said shoulders, a series of balls applied to each side of the thrust-collar, abutment-rings to press the balls a ainst such collar, and the easin and journa provided, respectively, with a ining and with a sleeve, one of which is adapted to hold the thrust-collar against its shoulder and the other of whi ch is adjustable to regulate the pressure of the abutment rings upon the balls.

I n the drawings the inner end of the bearing is shown closed by a collar upon the axle, and'the outer end is shown closed by a cap screwed upon the outer end of the hub.

The construction is particularly adapted for overhung bearings like those in wheel hubs upon the end of an axle; but it may also be used for the journals of lining shafts or spindles in the construction of machinery Where the shaft extends through the bearing. The thrust-collar in either case may be held rigidly upon the journal or in the casing, as may be preferred, the former construction being shown in Figure 1 and the latter construction in Fig. 14.

In the drawings, Fig. 1 is a view of the end of the axle, with a longitudinal section of the wheel-hub and its attachments. Fig. 2 is a cross-section of the bearing through the larger part of the axle. Fig. 3 is a cross-section of the bearing through the smaller art of the axle. Fig. 4 is a side elevation o the axle with the hub removed. Fig. 5 is a perspective View of the collar for closing the inner end of the bearing. Fig. 6 is a perspective view of the sleeve upon the axle adjacent to such collar. Fig. 7 is a perspective view of the thrust-collar; and Fig. 8, a perspective view of the sleeve upon the smaller part of the axle, which serves to hold such thrustcollar in place. Fig. 9 is an edge view, and Fig. 10 a side view, of one of the guide-collars for the thrust-balls. Fig. 11 is an edge View, and Fig. 12 a side view, of the adjusting-nut for the thrust-bearing and Fig. 13 is an edge view of the nut for clamping the thrust-col lar and the sleeve which holds it in place. Fig. 14 is a longitudinal section of a pedestal for a revolving shaft.

In Fig. 1, a designates the larger part of the wheel hub or casing of the bearing provided with flanges b to clamp the spokes thereon. A lining a is shown within the part a. A smaller part of the hub is marked a and is provided with a lining a, and a screwcap (1 is shown screwed into the outer end of the hub over the nut e, which is applied to a thread upon the end of the axle. The body or portion of the axle by which it is mounted on the vehicle-frame is designated g. The larger part within the hub portion a is designated f, and the smaller part within the hub portion a is designated f .The collar h is shown fitted upon the axle next a shoulder adjacent to the body portion 9 and provided upon its periphery with a groove in which a felt collar L is fitted to contact with the bore of the hub portion a, and thus, exclude dirt from the inner end of the bearing. The hub portion a is formed with a chamber extending to a shoulder j, and the lining a is extended against such shoulder. A sleeve lis applied to the corresponding ortion of the axle f, and a series of rolls m is tted to rotate between such sleeve and lining to support the hub upon the axle. The s oke-flanges b are nearly the midd e portion of the rolls m, so that the weight upon the bearing falls chiefly upon such rolls.

The usual roll-guide s is shown fitted to the rolls m in Figs. 1 and 2 to hold the rolls parallel with the axle. A thrust-collar n is aptween the larger portion f and the smaller portion f of the journal and is held firmly against such shoulder by a sleeve 1 upon the smaller end of the axle which presses a washer e against the sleeve Z:

shown projectin from the ub portion a over' plied to the axle against the shouldern bep portion of the axle and the nut 6 upon the The ehamber in the portion a of the axle in which the lining c is fitted is formed with a shoulder i at its rear end at a sullicient distance from the thrust-collar n to insert a ballguiding ring 0 and an abutment-collar 1) lll('ll rests against such shoulder. A similar hall-guiding ring 0 and an abutment-collar p are litted within the chamber upon the outer side of the thrust-collar, and the inner end of the sleeve 0 is iitted to contact with the collar p. Balls (1 are inserted in holes in the ball-guiding rings 0 and 0 and project from the opposite sides of said rings to conlat-t with the opposed faces of the abutmenti-ollars and the thrust-collar 11,.

A threaded collar 1' is fitted to a thread in the outer end of the wheel-hub in contact with the outer end of the lining c and has holes I" for turning it by a suitable spanner. The turning of the threaded collar presses the lining 0 against the outer abutment-collar p I and adjusts the contact of both sets of balls ith the thrust-collar a. The thrust-collar is held rigidly upon the axle by the sleeve Z and the nut e, and the abutment-collars are held rigidly in the wheel-hub by the lining c and the threaded collar 1", so that the wheel hub is firmly held from longitudinal movement when the thrust-bearing is suitably adjusted. v

A series of antil'riction-rolls m is inserted between the sleeve Zand the lining c and provided with the usual guide 8, such rolls and guide substantially filling the space between the outer abutment-collar p and the threaded collar r. The rolls m serve to lengthen the bearing of the wheel-hub upon the axle, and thus increase the resistance to any lateral strain upon the wheel-hub.

The reduction of the axle nearits outer end, which forms the shoulder 1/, serves in conjunction with the sleeve Z. and nut e to furnish a convenient means of securing the thrust-collar a rigidly and detachably upon the axle.

In practice the collar h and sleeve Z may be made separate from the axle and fitted tightly thereon; but the axle may be made without the sleeve and the collar it made integral thereon, if desired, as it is not essential that either should be removable. The thrust-collar n and the sleeve Z require, however, to be removable to permit the detachment of the wheel-hub from the axle for examination or repairs and to permit the assembling of the parts in manufacture.

By removing the nut e, the washer e, and threaded collar 1 the wheel may be pushed off of the axle with the entire thrust-bearing and the sleeve Z and such parts again laced upon the axle when restoring the whee to its operative position.

Where the thrust-collar is located between the two sets of rolls m m, as in the present design, the sleeve Z is an essential means of holding the thrust-collar rigidly upon the axle at a suitable distance from its outer end.

Fig. 14 shows the invention applied to a pedestal or stationary bearing for a revolving shaft. In this construction the thrust-collar is clamped in the casing (L of the pedestal by the lining e and nut r, and the abutment-collars p p are secured adjustably upon the shaft against the shoulder a by means of two nuts 6 and applied to the outer end of the sleeve 1. This arrangement is the reverse of that in Fig. 1. The rolls at opposite sides of the thrust-bearing are shown of the same diameter and length, and the shaft is extended through the bearing beyond the nuts and broken off to indicate that it may be extended at any required distance.

In Fig. 1 ball-guiding rings 7) p are shown; but such rings are not essential, as the balls may be guided by grooves in the thrust-collar and abutment-collars or in the abutmentcollars alone, as shown in Fig. 14. With such construction the abutment-collars are preferably secured together loosely with the balls and the thrust-collar by suitable fastenings, as the screws u, (shown in Fig. 14,) which prevents the displacement of the rings when setting the same upon the journal and permits the subsequent adjustment of the abutmentcollars as required.

It will be observed by reference to Fig. 1 that the sleeve l performs the double function of securing the thrust-collar 11 upon the journal while it also forms a bearing for the inner sides of the antifriction-rolls m. The

, lining 0 also performs a double function, as it forms the means for adjusting the thrustbearing with the aid of the nut r and also forms a bearing for the outer sides of the antifriction-rolls. By the use of such lining and sleeve a smooth steel bearing-surface may be furnished for the rolls, as is common in such constructions, and the same elementsnamel the sleeve and the lining-be employe to form and operate the thrust-bear- 1n The construction shown in Fig. 14 is so stantially the same, except that the arrangement of the parts is reversed, and the lining 0 serves to hold the thrust-collar in place, while the sleeve Z serves for adjusting the thrust-bearing; but this lining and sleeve also furnish the bearings for the outer and inner sides of the antifriction-rolls m, as in Fig. 1. It will be observed that in both the constructions (of Fig. 1 and Fig. 14) the shoulders n and t, whichcooperate with one another upon the journal and casing, both face in the same direction-that is, toward the end of the bearing in which the lining c is inserted and from which it is removable. This construction permits the thrust-bearin to be withdrawn from the casing and journa in the same direction simultaneously when the sleeve and lining are removed from the outer end of the casing.

to set of ant' Having thus set forth the nature of the in- 'vention, what is claimed herein is- 1. In a roller-bearing, the combination, with a casing and a journal havin the shoul- 5 ders n and 12 facing in the same irection, of

the thrust-collar n fitted to one of said shoulders, the abutment-rings with balls q fitted to the thrust-collar, the easin having the lining a and the 'ournal having t e sleeve Z with a 'ction-rolls m fitted between the same, and nuts operatin res ectively upon the lining c and upon t e s eeve Z., one of said nuts 0 erating to adjust the abutmentrings in re ation to the thrustcollar, the

I 5 Whole arranged and operated substantially as herein set forth.

2. In a roller-bearing, the combination, with a casing and ajournal havin shoulders n and t facing in the same directlon, of the 20 thrust-collar n fitted to the shoulder upon the journal, and abutment-tin p, p, with balls q fitted to the thrust-col ar, the abutment-ring 1) being fitted to the shoulder upon the casing and the casing having the lining a movable against the abutment-ring E, with the annular nut r for adjusting sue lining .and abutment-ring, and the -journal having CHARLES S. LOCKWOOD.
